By thermally or photolytically induced decomposition of O-acyl derivatives of N-hydroxypyridine-2-thione or other thiohydroxamic esters, in the presence of an excess of electron deficient olefins, 2-vinylcyclopentane derivatives were obtained. This sequence of addition/cyclization/elimination reaction is mediated by a phenylthio radical.
